SMOKE-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 521,054, dated June 5,1894.

7 Application filed June 21,1893. Serial No. 478,314. '(No modeh) &c.,may be stopped to avoid the emission of heavy products usuallydischarged in smoke and the Invention consists in the novelconstructions, combinations, and arrangement of parts as will behereinafter described and pointed out in the claims.

In the drawings Figure 1 is a top plan V ew of an apparatus embodying myinvention. Fig. 2 is a cross section on about line 2 -2 of Fig. 1. Fig.3 is a section on about l ne 3-3 Figs. 1 and 2 at right angles to theline of Fig 2, and Fig. 4. is a detail view.

In carrying out my invention I provide a plpe A leading from the smokechimney or other smoke discharge of the furnace, a receiving chamber Binto which the smoke is discharged, a blower O or the like being emnozzles serve to divide up the smoke discharged so that no great volumeis discharged at one point. This is desirable to avoid the formation oflarge bubbles in the water of the tank. The tubes of the nozzles leadinto the tank E which is covered and partly filled with water and thenozzle discharges open below the surface of said water so that the smokeis dlscharged below the said surface and directly Into the water so thatthe latter will catch all soot, sparks and similar solid matter. Astopplate F is arranged in the tank above the nozzles and resting eitherupon or slightly below the surface of the water its function being tobreak any bubbles that may rise from the nozzles and so prevent thesparks, 850., rising from the water by the bursting of said bubbles atthe surface. The tank may be filled by a pipe G or in other suitablemanner and- I prefer to provide an outlet pipe g to preserve the levelat the desired point. At one end of the tank is a soot outlet ordischarge H while a fan or blower I is arranged to discharge its blastinto the tank at 2' at the end opposite the discharge H, the inlet 41and outlet H being arranged at about the water level so that the blastwill tend to drive off the soot and similar accumulations upon thewater.

In operation the fans may be driven by electricity or other power sothat when the fire is started in the furnace the first smoke may betreated as well as that made after the fire has gotten well under way.

The receiving chamber B has at one end a door B, through which accessmay be had to I the said chamber for the purpose of cleaning out thecinders, &c., which will accumulate therein. The nozzle tubes connectwith the chamber about half way between its top and bottom, leaving areceptacle in the bottom of said chamber for such cinders as mayaccumulate therein.

In practice I prefer to employ at C a planing mill fan the smoke to goin the side of the fan. I also prefer to provide in the pipe A whichleads from the chimney an opening A and slide gate A to regulate thedraft in the furnace also to admit cold air to check the blaze.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is

1. In an apparatus substantially as described the combination of thewater tank,

the collecting chamber the nozzles leading ICO soot &c., and blastdevices discharging into the said tank such devices being arrangedrelative to said outlet substantially as described and adapted to forcethe soot 85c. therefrom all substantially as set forth.

4. In an apparatus substantially as described, the combination with thetank having an outlet at or about its water level, and a blast inletopposite said outlet, blast devices communicating with said inlet anddevices conducting the smoke &c. to such tank all substantially as andfor the purposes set forth.

5. In a smoke arrester the combination of the receiving chamber, havingthe nozzles, the water tank into which said nozzles discharge, said tankhaving a blast inlet and an outlet opposite the same, the tube or flueleading to WILLIAM P. SlI ANK.
